MANCHESTER, N.H. — He’s plotting an aggressive campaign schedule across several states, but Herman Cain has begun to outline a possible exit strategy from the race for the Republican presidential nomination.

The former business executive, facing a woman’s allegation of a 13-year extramarital affair, says a heavy emotional toll on his family – particularly his wife, Gloria, who he has not seen since the charge surfaced – could force him to call it quits. The shift comes as a growing chorus of would-be allies suggests he is no longer a viable presidential contender and Cain himself says fundraising has suffered.

Cain, a top-tier candidate just weeks ago, says he’ll decide in the next “few days” whether to abandon his White House bid, but not before he meets with his wife.

“Since I’ve been campaigning all week, I haven’t had an opportunity to sit down with her and walk through this with my wife and my family. I will do that when I get back home on Friday,” Cain told reporters gathered at his New Hampshire campaign headquarters Wednesday night. “I am not going to make a decision until after we talk face to face.”
